  • Toolcraft makes some of the best bolt carrier groups on the market today. Precision manufactured on state-of-the-art CNC machinery in North Carolina, Toolcraft BCGs are trusted by the US Military and carry a lifetime warranty.

    A bolt carrier group is only as good as it’s bolt. The bolts used in these BCGs are manufactured from Carpenter 158 steel, the same high strength steel that is specified by the US Military for M16 bolts. Also see our 9310 steel Black Nitride BCG.

    Finish is Black Nitride which is a metal treatment that produces a case-hardened surface. The resulting finish is extremely wear and corrosion resistant and very slick. This means less friction and smoother, more reliable function. The rich black color on these BCGs looks fantastic and cleans up much easier than a phosphate finish. Also see our Nickel Boron BCGs.

Above and Beyond

Everyone knows that Toolcraft makes high quality bolt carrier groups, and this purchase was no exception. What was different for me, being my first experience with SpiceTac, was dealing with a company that truly puts its customers first. Never have I seen a company so dedicated to making my purchase a pleasure, rightfully earning repeat business. David, I can't thank you enough for the insanely fast shipping time and personal attention to detail that came along with my order. I have since spread the word around to some friends who also placed orders with you, and their experience was exactly the same as mine, so it's definitely no kind of accident or fluke. This man truly cares about his customers and deserves more praise than I know how to put into words. In short, you've earned a customer for life. Thank you so much.

Awesome

Great product and Excellent customer service. The person that filled my order noticed that I live in Va. and wrote where they were in the military and stationed in Va. Great to see someone take the time out of their day to write a simple note. I look forward to placing my next order.

Excellent experience!

I received my BCG 2 pack a couple days after ordering and I must say, everything the reviews say is right. The product quality is great! The price was awesome! Delivery time was fast! And the personalized note was a cool touch. I showed my wife the notes left in my order and as a business owner, she was as impressed as I was at the level of care and service SpiceTac takes for its customers. I will definitely be ordering again!
